1 Many reports have shown that stimulation of the kappa opioid receptor (KOR) suppresses development of analgesic tolerance to morphine. Morphine opioid receptor kappa 1 Homo sapiens
2 Many reports have shown that stimulation of the kappa opioid receptor (KOR) suppresses development of analgesic tolerance to morphine. Morphine opioid receptor kappa 1 Homo sapiens
3 Here, we studied the KOR-mediated inhibition of morphine tolerance during repeated morphine treatment, with a focus on desensitization of the receptor. Morphine opioid receptor kappa 1 Homo sapiens
4 Here, we studied the KOR-mediated inhibition of morphine tolerance during repeated morphine treatment, with a focus on desensitization of the receptor. Morphine opioid receptor kappa 1 Homo sapiens
5 These results indicate that stimulation of KOR caused by repeated morphine treatment either inhibits MOR desensitization or accelerates recycling of MOR on the cell surface, thereby suppressing morphine tolerance. Morphine opioid receptor kappa 1 Homo sapiens
6 These results indicate that stimulation of KOR caused by repeated morphine treatment either inhibits MOR desensitization or accelerates recycling of MOR on the cell surface, thereby suppressing morphine tolerance. Morphine opioid receptor kappa 1 Homo sapiens
7 These results suggest that the mechanisms underlying KOR-mediated inhibition of analgesic tolerance to morphine may be partly due to suppression of PKC activation and prevention of receptor desensitization. Morphine opioid receptor kappa 1 Homo sapiens
